Title: Artificial snow facilities
Inventor: MORIOKA KOJI
IPC: A63C19/10
Filed: 1995-05-01
Abstract: PURPOSE:To prevent the breakage of a snow layer cooling piping based on the scraping of a snow layer by a sliding tool or snow surface maintenance equipment by burying a net material under the surface of the snow layer apart upward from the snow layer cooling piping. CONSTITUTION:A laminated layer 19 of sand or sand-like material is formed on a floor 2 having snow layer cooling pipings 5 juxtaposed on the floor surface in the state where the snow layer cooling pipings 5 are buried therein. The laminated layer 19 is then impregnated with water, and the impregnated water is cooled and frozen to form a snow layer 4 on the laminated layer 19. In such artificial snow facilities, a net body 20 is laid in a position separated upward from the snow layer cooling pipings 5 in the state where it is buried under the snow surface of the snow layer 4. Thus, the snow layer cooling pipings 5 can be effectively protected by the high strength of the laminated layer 19.

Title: Distance detector
Inventor: SATO SHUNICHI
IPC: G01C3/06
Filed: 1988-04-30
Abstract: PURPOSE:To shorten the length of a light path using relatively small parallel planar plates, in a distance detector for detecting a focus error, by arranging a concave lens between two parallel planar plates to change the convergent angle of converging light. CONSTITUTION:When the distance between an objective lens 3 and a data recording medium S is shorter than a focus distance, the cross-sectional shape of luminous flux becomes an oval shape long in an X-axis direction and, when said distance is longer than the focus distance, said cross-sectional shape becomes an oval shape long in a Y-axis direction. Therefore, the distance be tween the objective lens 3 and the data recording medium S can be detected from the output of a four-split light detector 7. In this distance detector 1, only a parallel planar plate 6 is inclined at a large angle of inclination by parallel planar plates 4, 6 and a concave lens 5 to obtain large astigmatism quantity. Therefore, it is unnecessary to incline both of two parallel planar plates at a large angle of inclination and a distance can be detected with high accuracy in spite of a short light path.
